Liang Xie commented on HBASE-11346:
-----------------------------------
How to think: most of the new HFiles have a high probability to be compacted
soon, so maybe this proposal will bring more block cache eviction ?
> Enable cacheonwrite for index and bloom blocks by default

> Key: HBASE-11346
> URL: https://issues.apache.org/jira/browse/HBASE-11346
> Project: HBase
> Issue Type: Improvement
> Components: regionserver
> Affects Versions: 0.99.0, 0.98.4
> Reporter: Nick Dimiduk
>
> Theory is, this will reduce the cost of compactions on a mixed workload
> cluster, reducing the number of seeks for the first blocks from the new HFile
> from ~4 to ~1.
